Core and Feature Requests

Libretro Cores
#877

I have mentioned this before in the past but i would like to repeat it again.

The core options.opt system needs to work in the same way as regular overrides do.

Right now they don’t. If i change one option for a certain game and save it as a “game.opt” it also saves all the other options that i didn’t change in the .opt file. Which means if i change something else in my general “core.opt” to affect all games, that particular game will still have the old option saved so it won’t be affected.

With overrides, ONLY the changed option is saved and it reads all the others from the default.cfg. This way if i change something else in the default core.cfg, it will affect all games, even the ones that have their own overrides for other options.

If the .opt files can work like overrides do, it would be a massive upgrade for RetroArch.

Hi, i don’t find any changes. Is there an option for that new deinterlace feature ?

i loaded the cores from here… https://buildbot.libretro.com/nightly/linux/x86_64/latest/

#879

The commits clearly haven’t been merged yet, so for the time being you need to build it yourself.

Thank you. Can you guess when it will be available at buildbot? I have no clue howto build cores.

#881

Agreed. It’s so annoying that, most of the time, I delete my opt file and rebuild it again from the whatever is my new default. It’s surprisingly less bothersome.

Yeah, that change would be a good thing!!!

I noticed it Just few week ago while setting up geolith core-options for different content. All settings get saved (and loaded) instead of just the setting you changed (+ using general core options overrides)

Thank you, the deinterlacer works, but has some kind of flicker to it. Swanstation seems not to have these artefacts.

@Awakened can you confirm that there is a difference between “deinterlacing bob” on beetle psx hw vs “interlacing off” on swanstation ?

but it looks better than without a deinterlacing filter!

EDIT: i found an issue with tekken 3 and that new bob filter. the intro scene was doubled with one picture stacked on top of another.

Flicker is what Bob does. No idea what swanstation is supposed to be doing, and surely this is not the best place for bug reports. Haven’t seen that split screen yet with anything I’ve tested, and it is simply the Mednafen/Beetle internal option.

You are right, sorry. I created an issue on guthub

#888

I tried the bob method in both beetle cores, but it vibrates and causes more blurring than using weave with the misc/deinterlace slang shader. I think I might prefer weave without the shader; the combing artifacts are a bit more palatable to me than the blur/vibration effect.

SwanStation’s interlacing off is still the best. I’m just not sure how it’s implemented. I’d assume it’s like the PS2 emulator’s per game hacks that force games into 480p.

Kronos has an optimized bob method called adaptative, it uses some kind of threshold to prevent that vibration, someone (not me) could probably backport it to other emulators.

I found a brain fart and managed to improve the bob blurring a bit, and it is completely gone now in 240psuite alternating test for example. Soon to be merged hopefully for both cores.

I will try when it available on buildbot. I wonder If it can also fix my issue with Tekken 3 beside being less blurry. Thanks for your efforts.

#892

Yes the Tekken issue is also covered. 240psuite suffered from the same problem of not detecting the current interlaced mode properly/completely for whatever reason…

Tested Astra Superstars and Tobal 2 with the updated bob and it looks much clearer now. Better than the deinterlace shader. Thanks!

Hello!!!

Is there any chance to include Nuked-OPM in the sound emulation of the px68k core? This will be a fantastic update. About the MIDI feature, it has a small but noticeable delay (I test Akumajou Dracula with LA and GS modes in MUNT and Nuked-SC55). It would be great if this delay could be fixed. Anyway, this is an excellent X68000 core.

Thanks!!!

try to see if the windows core works for you. but it would be nice to have a core that launches the game directly like that FF7 Phone Game recreation core.
